The Arms Deal Update for Counter-Strike: Global Offensive is live, adding in a Team Fortress 2-style system of random drops, over 100 new weapon skins, two new stock weapons, and a purchasable item that helps fund competitive play.
The new weapon skins will drop randomly while you play CS:GO, much like new items in Team Fortress 2. Unlike TF2, all of the modifications are purely cosmetic. You will also occasionally find weapon cases, similar to TF2's crates, which must be opened by a key. These come in two styles: standard variety, and a special eSports case. The proceeds from eSports case keys will go towards larger prize pools and greater visibility for competitive CS:GO.
It's not all just paint jobs and microtransactions, though. We're also seeing the return of the silenced variants for the M4A1 and the USP, which feature a smaller price tag and magazine size than their louder brethren.
Arms Deal is available now, and you can read more about it on the official announcement page .
